BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is related to a method for forming caves on aconstruction and a body made with the caves by the method. In themethod, a fluid (which can be a gas or a liquid) is filled into anenvelope and the envelope is laid in a grouting mold cavity. After thegrout filled in the grouting mold cavity is hardened, the envelope isdeflated or drained of the fluid to achieve the construction with thecaves.

2. Description of the Prior Art

In the existent working method for construction, generally planemoldboards are established to form a grouting mold cavity. Properstructures such as reinforcements are built in the mold cavity and thenconcrete is grouted into the mold cavity. After the concrete ishardened, the moldboards are disassembled to achieve a construction withplane wall faces. Such working method is widely applied to gutters, hillslopes, bridges, piers, wave absorbers, etc. The construction made bythe conventional working method has plane and monotonous outer face.Creatures such as plants, birds, reptiles, fishes, etc. can hardly liveon such plane wall faces. As a result, such construction fails to meetthe requirement of natural field and may seriously destroy a localecological environment. This should be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 6 shows the method for forming caves on a construction of thepresent invention. The method includes steps of:

1. preparing an envelope 1 with a shape corresponding to the shape ofthe cave to be formed on the construction, a fluid such as a gas or aliquid being filled into the envelope 1 to form a solid envelopeoccupying a certain space;

2. establishing construction moldboards 2 to form a grouting mold cavity20;

3. grouting the grouting mold cavity 20 with a filling 3, after thefilling 3 reaches a certain height (as shown by B of FIG. 6 ), theenvelope 1 filled with the fluid being placed in the grouting moldcavity 20 in a predetermined position;

4. further grouting the filling 3 into the grouting mold cavity 20 (asshown by C of FIG. 6 );

5. detaching the construction moldboards 2 after the filling 3 in thegrouting mold cavity 20 is hardened; and

6. deflating or draining the envelope 1 of the fluid or taking out theenvelope 1 to achieve a construction 4 with the cave 41 (as shown in Dof FIG. 6 ).

In the above grouting step, the filling 3 can be concrete, resin or foamrubber. This is not limited in the present invention.

Referring to FIGS. 1 to 5, the envelope 1 of the present invention canbe made of plastic or rubber or other recoverable or naturallydecomposable material. After filled with the fluid (such as air, water,etc.), the envelope 1 becomes a solid envelope. When grouting thefilling 3, the pressure of the filling 3 will irregularly or regularlycompress and deform the envelope 1. After the filling 3 is hardened, theenvelope 1 will form the irregularly or regularly shaped cave 41 in theconstruction. The cave 41 serves as a place in which creatures such asfishes, shrimps, birds, reptiles, etc. can accumulate and grow.

Referring to FIGS. 1 to 5, the envelope 1 of the present invention canbe made with various regular or irregular shapes. FIG. 1 shows anenvelope 1 applicable to the channel reef 413 as shown in FIG. 6. FIGS.2 and 3 show envelopes 1 applicable to the wall caves 414 of theretaining walls as shown in FIGS. 8 and 9. FIG. 4 shows an envelope 1applicable to the draining hole 411 of the retaining wall as shown inFIGS. 8 and 9. FIG. 5 shows an envelope 1 applicable to the channel reef413 of the retaining wall as shown in FIG. 7. Alternatively, manydifferent shapes of envelopes 1 can be made and applied to differentfields. This is not limited.

After filled with the fluid, the envelope 1 of the present inventionbecomes a solid envelope having irregular or regular shape such ascircular, cylindrical, polygonal, etc. The shape of the envelope 1 isnot limited. In addition, the material of the envelope 1 is also notlimited. For example, the envelope 1 can be made of rigid rubbermaterial (such as the material for making a soccer) or the rubbermaterial for making a tire (without inner tire). An inflating nozzle 11can be added to the envelope 1 to facilitate inflation. It is known thatafter inflated, a common tire can bear a truck of several tons.Accordingly, the envelope 1 made of the tire rubber can also bear verygreat pressure of the concrete. In order to fix the envelope 1 in apredetermined position to facilitate grouting, the envelope 1 can beintegrally formed with several fixing rings 12. When embedded, an ironwire can be passed through the fixing ring 12 of the envelope 1 to tieand fix the fixing ring 12 on the a reinforcement (not shown). Theinflating nozzle 11 is directed upward or outward and prevented frombeing embedded in the filling. Furthermore, a liquid such as water andoil (for example, oil used in an oil cylinder) can be filled into theenvelope 1 to bear very great grouting pressure. In order to easilydetach the envelope 1 from the concrete after the filling is dried, agrease such as construction-used moldboard grease can be previouslypainted on the outer face of the envelope 1 to facilitate detachment ofthe envelope 1 from the concrete. The envelope 1 can be then taken outfrom the cave 41 and repeatedly used. Alternatively, an inflatedenvelope 1 with larger volume can be embedded in the filling in a lowerposition. After grouting, the envelope 1 with larger volume suffersgreater pressure and is minified to a preset volume.

In the method of the present invention, after the filling 3 (such asconcrete) is hardened, the envelope 1 can be taken out or deflated ordrained to form the cave 41 on the construction. Alternatively, afterthe moldboards 2 are disassembled, the envelope 1 can be naturallydecomposed or reformed or corroded to remove the envelope 1 from theconstruction and form the cave 41.

The method of the present invention is applicable to the channel reef(or gutter) as shown in FIGS. 6, 7 and 12 or the slope retainer wall asshown in FIGS. 8 and 9 or the sluice as shown in FIGS. 10, 11 and 13.This is not limited in the present invention.

Referring to FIGS. 10 and 11, two ends of the envelope 1 can abutagainst two lateral moldboards 2. The concrete is grouted between themoldboards 2. After hardened, the envelope 1 is removed or deflated ordrained to form a sluice 412 through the construction.

The method for forming caves on the construction of the presentinvention includes steps of: preparing an envelope corresponding to thecave to be formed on the construction; filling a fluid such as a gas ora liquid into the envelope to form a solid envelope; embedding theenvelope in the construction to be grouted to define a grouting moldcavity; and deflating or draining the envelope of the fluid after afilling filled in the grouting mold cavity is hardened to achieve aconstruction with the caves.

The caves 41 of the construction can be draining holes 411, sluices 412,channel reefs 413, wall caves 414 or any other cave with various shapes.

According to the above arrangement, the present invention has thefollowing advantages:

1. The cost for the envelope of the present invention is low. When notfilled with any fluid, the envelope is flat and light and can be easilystored and transferred.

2. The envelope of the present invention can be repeatedly used.

3. The method of the present invention can be easily and quicklyperformed to lower working cost.

4. The method of the present invention can form irregular or regularcaves on the construction, which serve as a living or growth environmentfor creatures in natural field.

5. The body made with caves by the method of the present invention canform a fish reef in the sea to serve as an artificial fishing field fordevelopment of fishery.

6. The present invention is widely applicable to various constructionssuch as retaining wall, gutter, wave absorber, etc.

The above embodiments are only used to illustrate the present invention,not intended to limit the scope thereof. Many modifications of the aboveembodiments can be made without departing from the spirit of the presentinvention.
